qam modulation and demodulation ppt

Amplitude/phase-shift keying (APSK) is a specific form of quadrature amplitude modulation where constellation points lie on concentric circles.Demodulation of APSK consumes slightly more clock cycles than the PSK and QAM demodulators. QAM Stands for Quadrature Amplitude Modulation. QAM is both an analog and a digital modulation method.170: Basics of IQ Signals and IQ modulation demodulation - A tutorial - Продолжительность: 19:00 w2aew 145 674 просмотра. Hi guys, In this Lecture concept of Quadrature Amplitude Modulation (QAM) are elaborated. After this lecture you will be able to understand Significance of QAM including Modulation/Demodulation Modulation and demodulation. medium, it would be difcult for their intended receivers to extract the signals reliably because of interference.Figure 14-16: Quadrature Amplitude Modulation (QAM).
